The results indicate an improved rating for components with a high recycling potential. The method proved to be able to include recycling options into the focus of the assessment, giving an incentive for closing material cycles in the building industry.
The study was commissioned by the Swiss Aluminium Association and was done in co-operation with:
- Schweizerische Metall-Union (SMU)
- European Aluminium Association (EAA)
- Aluminium-Verband Schweiz
- Alcan Technology & Mgmt. AG
- Alcan Allega AG
- Solenthaler Recycling AG
The results were presented at the 12th case study symposium of SETAC Europe in Bologna, 11. - 12. Jan 2005 as a poster. and at the 4th SETAC World congress in Portland 2004 as platform presentation. The study is originally in German ("Graue Energie" von Bauprodukten aus Aluminium unter Berücksichtigung der wertkorrigierten Substitution) and can be downloaded here.
